Dissolve yeast in 1 cup warm water and let stand for 5 minutes.

Heat milk and 2 cups of water to lukewarm.

In a large bowl, combine the lukewarm milk and water mixture with salt, oil, and honey.

In a separate very large bowl, mix together white flour, whole wheat flour, and soya flour.

Gradually add the wet ingredients to the dry ingredients, stirring until a dough forms.

Add the yeast mixture to the dough.

Knead the dough by hand on a lightly floured surface until smooth and elastic (about 8-10 minutes).

Place the dough in a greased bowl, turning to coat. Cover and let rise in a warm place for about 1 hour, or until doubled in size.

Punch down the dough and divide it in half.

Shape each half into a loaf and place in greased loaf pans.

Cover and let rise again for about 30 minutes.

Preheat oven to 350°F (175°C).

Bake for 30-35 minutes, or until golden brown and the internal temperature reaches 200°F (93°C).

Let cool in the pans for a few minutes before transferring to a wire rack to cool completely.
